Sanofi claims its Covid vaccine will not need supercooling, can be kept in fridge
The Pfizer vaccine is "a little more advanced" in the development process, said Bogillot, France Chief of Sanofi, but "one laboratory is not going to be able to supply the doses for the whole planet.";
New Delhi: The coronavirus vaccine being developed by Sanofi will not need to be super-cooled and a normal refrigerator will suffice, the Paris-based drugmaker's France chief Olivier Bogillot said Sunday (Nov 15).
His comments came days after American pharmaceutical giant Pfizer and its German partner BioNTech announced that their vaccine had proven 90 percent effective in preventing Covid-19 infections in ongoing Phase 3 trials involving more than 40,000 people.
The companies said they expect to supply up to 50 million vaccine doses globally in 2020, and up to 1.3 billion doses in 2021.
However, Pfizer's vaccine must be stored at -70 degrees Celsius or else it falls apart, well beyond the capability of most hospital freezers let alone domestic appliances.
Rachel Silverman, a policy fellow at the Center for Global Development, has already warned that maintaining the Pfizer vaccine's "ultra-cold chain" from the factory to patients' arms constitutes "an enormous logistical challenge even in the West".
